The Sator Square is a Latin palindrome dating from Roman times, featuring the words SATOR AREPO TENET OPERA ROTAS. While not entirely clear, the meaning of the sentence is likely: "The farmer, Arepo (a proper name), uses his plough as his form of work." Mystical connections have been suggested with the square, from Christian anagrams (the letters can be rearranged to form a cross of "Pater Noster"'s (Lord's Prayer) with two As and two Os left over, taken to stand for Alpha and Omega) to folk magic charms (a common belief was that palindromes confused the devil). It can be read in multiple ways: right-to-left, left-to-right, up-to-down, down-to-up, or even boustrophedon (left to right on one line, and right to left on the other). A rearrangement may invert or otherwise change the order of the words, but because word order is relaxed in Latin, the meaning stays the same.
